Need alittle assistance with Rotor Set Screw

Howdy Audi friends, I got new rotors and pads for my 07 A4, theyre drilled slotted and vented rotors. I replaced the rear with no issues. The set screw fit perfect. But upon doing the front, the set screw is way too small. The holes seem to be universal lug so all the holes of the rotor are about the same size as the bolt that connects wheels to the hub. <a href="https://downloadnox.com/">Nox</a> <a href="https://showbox.red/">ShowBox</a> <a href="https://mobdro.onl/">Mobdro</a>

I was curious if theres larger rotor set screws anywhere I can purchase for the front?
